Great Egg Harbor Inlet and Corson Inlet, located in southeast New Jersey, have been plagued with hazardous navigation conditions and erosion problems. Numerical techniques were used to investigate the tidal hydrodynamics of the inlet complexes for existing conditions as well as for proposed improvement plans. The physical size and complex geometry of the study areas required a simulation model that could be economically applied. Consequently, an inherent part of the study involved development of a numerical model (WI model) based on an implicit finite difference formulation. The model includes treatment of moving boundaries and subgrid-scale barriers. A comparison study with a well-known explicit finite difference tidal model was performed to assure the implicit model's reliability and cost effectiveness. Having demonstrated the WI model capability, the next phase of the study concerned application of the WI model to Great Egg Harbor and Corson Inlets to quantitatively predict the tidal hydrodynamics (exclusive of salt and sediment transport) for existing conditions and various improvement plans. The basic improvements for each inlet are similar. In general, they provide for: (A.) An upcoast jetty with a weir section for navigation protection and beach erosion control. Bayward of the weir section a deposition basin would be dredged to impound sand transported across the weir section. Periodic maintenance dredging of the deposition basin would provide sand for nourishment of adjacent beaches. (B.) Construction and maintenance of specified navigation channels. (C.) A downcoast bulkhead and jetty system together with an optional development of landfill area adjacent to the bulkhead for public recreational use. Results of the numerical computations indicated that the systems proposed for Corson Inlet appear to function equally well and no detrimental effects were noted. For Great Egg Harbor Inlet, a concentration of ebb flow toward the upcoast deposition basin and structure was noted, suggesting a potential problem which should be recognized for the proposed plans. Time histories of tide elevations and velocities are presented for selected stations throughout each inlet complex. Circulation patterns at each half hour during a complete tidal cycle are presented in film form for the verification conditions and for each plan._x000D_ _x000D_ NOTE: This file is large.
